REQUIRED TOOLING
To successfully cable the Fischer MiniMax Series tooling is required to insure proper alignment of the
various parts that need to be assembled. The below instructions are valid for cable assemblies on both
plug (MP11) and cable receptacle (MR50) for both sizes 06 and 08, independent of locking or coding.

PROCEDURE
1
Cut the bend relief to adjust it to the cable diameter.
Slide the bend relief +clip + back nut + insulator
tube on the cable as shown in the picture.
2
Strip the cable jacket to 14mm.
(for both size 06 and 08).
3
Pull back the braid over the jacket.
We recommended to use a clear tape to hold the
braid on the jacket.
Position Trim back Strip
External - 1.5mm
Intermediate 1.5mm 1.5mm
Central 3mm 1.5mm
4
Trim back and strip the conductors according to
following specifications:
Illustration shows 19 contacts.
Same principle of up to 3 levels
(external, intermediate, central) applies
for all MiniMax configurations.
If only 1 level, use External level.
If 2 levels, use External and
Intermediate levels.
5
Solder all conductors to the contact block.
See technical specifications for wire numbering.
In order to use the correct numbering scheme,
please not that the landmark used to fix the
contact block on the insulator tube (see arrow
in the picture on the right) is OPPOSITE to the
grounding pin reprensented on the PCB hole layout
diagram in the MiniMax technical specifications.

FISCHER MINIMAX SERIES
PROCEDURE
6
Slide the insulator tube onto the contact block using
the «poka yoke» mismatch protection for correct
orientation.
7
Pull back the braid from the insulator tube on the
cable jacket.
8
The insulator tube can be glued on the contact
block for better retention.
(Loctite 406 glue recommended)

6
FISCHER MINIMAX SERIES
PROCEDURE
9
Potting of the insulator tube through the hole
(upper limit = blue line).
Insulator tube can be pre-heated if necessary.
We recommend to use a heat shrinkable sleeve
to cover the filling-hole to avoid potting material
coming out of the hole once potted.
Curing time and conditions according to your
potting material.
10
Put the O-rings on the contact block
(with grease) and on the housing.
11
Initial setup
Make sure the support tool (130254) is properly
centered on the table press (130257) using the
alignment tool provided.
Insertion of the insulator tube with the press.
Insert the insulator tube into the housing with the
multifunction press until it clips on.
Use the appropriate tool set for Minimax 08
(130253) or Minimax 06 (130252).
“tool 1” for MP11
“tool 2” for MR50
“tool 3” “Housing” facing up
Make sure to align the nose of the insulator with
the housing before the insertion operation.

12
Pull up the braided shield.
13
Cut off the braided shield to a length slightly infe-
rior to the O-ring location.
14
Fitting of the backnut with the press.
Press-fit the backnut with the multifunction press
using the appropriate tool set for Minimax 08
(130253) or Minimax 06 (130252).
“tool 1” for MP11
“tool 2” for MR50
“tool 3” “Back nut” facing up
The backnut is now in position.

FISCHER MINIMAX SERIES
PROCEDURES
15
Potting of the back nut through the hole.
First fix the boot bend relief clip on the back nut.
Make sure the potting material entirely fills the
space between the clip and the nut, all the way to
the top of the clip.
We recommend using a heat shrinkable sleeve
to cover the filling-hole to avoid potting material
coming out of the hole once potted.
Curing time and conditions according to your pot-
ting material
16
Slide the boot bend relief over the back nut until it
firmly hooks on the clip.
Congratulations with your terminated MiniMax.
